Recently, fluidic thrust vectoring control is popular for a micro space launcher propulsion system due to its several advantages such as better control effectiveness, few or no moving mechanical equipment, and fast dynamic responsiveness. The dual-throat nozzle is an especially effective method in the fluidic thrust vectoring control field, utilizing another convergent section to connect with the divergent portion of the conventional convergent-divergent nozzle. By injecting secondary flow asymmetrically at the upstream nozzle throat, a new aerodynamic minimum area appears at the downstream of the geometric throat minimum area and the sonic-plane skews, therefore vectoring the primary flow. In the current work, numerical analysis is conducted to investigate the effects of the injection angle on dual-throat nozzle vectoring performance in a three-dimensional supersonic rectangular nozzle. To establish the reliability and accuracy of the current research methodology and turbulence model, the numerical results were validated against experimental results from the open literature. Numerical results calculated with the shear stress transport k-ω turbulence model shows an excellent agreement with experimentally measured static pressure along the upper dual-throat nozzle surface in the symmetry plane. Five injection angles are discussed and critical performance variations are quantitatively and qualitatively analyzed, including the pitching angle, injected mass flow ratio, system resultant thrust ratio, resultant pitching thrust efficiency, Mach number contour and streamline in the symmetry plane, and Mach number contours at different slices. Some useful conclusions are offered for fighter jet designers.
